If we open the 1861007035.xml file and modify the name from Professional ASP.NET 1.0 Special Edition to Pro ASP.NET 1.0, our file change notification would be enforced and the XmlDocument storing the XML from our file would be removed from the Cache. Requesting our ASP.NET page[r]

From March 2002, libraries of selected Wrox books will be available online at Wroxbase.com, based on technologies that you use everyday. The initial set of libraries will be focused on Microsoft-related technologies. You will be able to subscribe to as few or as many libraries as you require, and ac[r]

Page ViewState In this new round-trip model of Web Forms, there are potentially more interactions with a server than there would be in a traditional browser-server inter[r]

sr.Close() %> In this code we're using the FileMode.Open parameter to tell the FileStream that we're opening an existing file. We use the ReadLine method to read two lines from the file and write them to our ASP.NET page using Response.Write. MemoryStream A memory stream allows us to rea[r]

Creating List Content with ListItem Objects Instead of populating the list using data binding, we can just use <option> elements in the traditional way: <select id="MyControl" runat="server"> <option value="value1">Option 1 Text</opt[r]

txtHeight.Value = MyControl.Height.Value If we want to know the type of unit, we can query the Type property of the Unit object, but this returns the integer equivalent of the UnitType enumeration. For a unit in pixels, for example, this property returns 1. However (in a similar way to the e[r]

However, if we do specify an explicit cast on an assignment such as new, this will override the checks performed by the compiler. If t[r]

We've also looked at the enhancements to the existing languages that bring them into line with the CLR and CLS, how these features are compatible across all languages, and the benefits they bring. Features such as cross-language development, debugging, and tracing may not seem that great if you only[r]

All we do is ensure that it's converted to a string and assign it to the Page-level "sort order" variable, then call the routine that recreates the DataView and bind[r]

Clear-Text/Basic Authentication Whereas Windows NTLM authentication sends a hash of the credentials, this hash can only be computed by an application that is able to create the hash. Some Web Service clients may not wish to use NTLM authentication, but are likely[r]

as simple as right-clicking on localhost in the Solution Explorer and selecting rename. Next, we declare a local variable, indexIntoSeries.
